Description

We will discuss a calculation of large-Nc masses of light mesons from the QCD sum rules. Two methods based on the use of linear radial Regge trajectories will be presented. We put a special emphasis on the appearance of pole near 0.5 GeV in the scalar isoscalar channel which emerges in both methods and presumably corresponds to the sigma-meson.
